PERFORATION-CLEANSING RECIIPROCATING-BRUSH APPARATUS.

Applicationfiled. October 11, 1822. Serial No. 593,677.

T 0 all whom 2'23 may concern:

Be it known that we, THEODOR Kooi-r, a

citizen of Germany, residing at: Newark, in the county of Essex and State of New,

Jersey, and KURT K. LEDIG, acitizen of the United States, also residing at Newark, in the county of Essex and State of New J ersey, have invented certain new and useful Improvements in Perforation-Cleansing Reciprocating-Brush Apparatus, of which the following is a specification.

This invention relates to devices for mechanically cleaning a plurality of fine perforations, in a thin plate, metallic'gauze or like article,without damaging the same or enlargingthe area of the openings or inter-v stices. a

While the apparatus hereafter disclosed is broadly applicable to a considerable range of articles, as gratingsfgauzes, perforate plates, etc, irrespective of the shape of the openings or ho'w closely they may be arranged, the original purpose of the invention is to cleansethe openings in the end wall of an appliance technically known as a spinneret, used for extruding exceedingly minute-filaments or threads of the viscous substance used in making artificial silk.

*This substance or composition, in a semiliquid or jelly like condition, is forced under great pressure into a thin walled annulus having a plurality of minute circular openings disposed in equal spaced relation in its flat bottomed wall, the extruded plastic filaments hardening almost at once in the air due to the volatilization of the liquid constituents of the mass.

Notwithstanding care in preparing the ingredients and mixing the mass, occasionally a small not properly incorporated particle will obstruct one of the passages, which are approximately .004 of an inch in diameter, one of the threads may congeal too rapidly,

or other causes arise which compel cleansing of the line orifices.

- This operation entails removal and substitution ofthe spinneret, and, in view of thinness of the wall, the small diameter of'the hole and that it must be essentially cylindrical. ordinary methods of cleaning cannot be safely used; a brush having fine but stifi bristles directed lengthwise against the perforate wall is considered the only safe method, the brush being used dry or 1noistened with a solvent for the substance as may be preferred.

Thus one of the objects of the invention is to provide an apparatus suited to engage a removable brush and to rapidly move the same in the direction of length of its bristles reciprocatively.

Another purpose is in the provision of means for adjustably supporting the perfo rate articles in register with the brush and for readily interchanging the articles.

A further aim is to provide a support capable of receiving a plurality of the articles to be cleansed and associate therewith means for automatically and intermittently advancing the same within the scope of brush action.

These and other related objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in which Figurel is a plan view of an apparatus made in accordance with .the invention.

Figure 2 is a side elevational view of the same.

fFigure 8 is a front elevational View there- 0 Figure 4 is a plan view showing a modification in holder structure.

Figure 5 is a partial side, partial sectional view of the modification.

Figure 6 1s a perspective view of the spinneret drawn to an enlarged scale with the perforations exaggerated.

In'these drawln s the numeral 15 designates an elongated rectangulariflat base plate, on one portion of which is secured an electric motor 16.

Bolted to the opposite end of the base are the feet 17 of an arched column-18 having at its center a raised upright 19 terminating in opposed outstanding flanges 20 and surmounted by a removable cap 21.

An outstanding lug 22 extends to the front from one of the members of the arched column and a similar but thinner lug 23 projects in like manner from the other member.

A stud 24.- is rigidly set in the lug 22 to *extendupward and rotatably mounted on the stud is a hub 25 formed with a plate lever 26 adap ed to engagethe upper sur I face'of the lug 23, the lever-b tending laterally outwia'nd' teiridjefaipon the I *fte'nding to -for eing notched,,as at 27 to'receive the body of a screw 28; the head of which acts as a retainer for the lever. v
